VoIP Telephone.
External power supply – 24-48Vdc, 200mA
NOTE: Earlier models (produced prior to May 2008) are 48Vdc only.
Check the connector legend as shown above. If it is marked "AUX" it can
accept voltages between 24 and 48V DC. If it is marked "48V" it is 48V only.
Control inputs - for connection to voltage free contacts only. Internal pull-up
resistor source current = 300uA. These inputs form part of a SELV circuit and
precautions must be taken to prevent hazardous voltages being applied to
these circuits
LAN connection - RJ45 on Cat5 or Cat5e UTP cable
All other connections - 0.14mm² to 2.5mm² (26 to 14awg) for rigid/solid
cables, 0.14mm² to 1.5mm² (26 to 16awg) for flexible/stranded cable.
6.8. VR and Help Point Installation
1. To prepare for installation, remove the faceplate from the rear enclosure
(if supplied) by undoing the four retaining screws. A 3mm Allen key is
required.
2. VR and Help Point telephones are intended for vertical installation to a
wall or pole or flush-mounted into a vertical surface. Select the required
mounting method (section 5) and mount the rear enclosure first where
applicable.
3. Route the required cables through glands as appropriate, and make
connections following section 6.9. When fitting mains wiring to this
product that is not wholly run within trunking, it is important that the
strain relief is correctly installed and tested to ensure there will be no
disturbance to the wire terminations. As a minimum the cable must
withstand a pull of 60N (approx 6kg force or 13.5lbf) without visible
movement. If conduit is used, mains cables must be secured elsewhere.
4. Re-fit the faceplate ensuring a weatherproof seal
